"Cheerfulness is the support of our strength; in the joy of the Lord are we strong. It acts as the remover of difficulties. It is to our service what oil is to the wheels of a railway carriage. Without oil the axle soon grows hot, and accidents occur; and if there be not a holy cheerfulness to oil our wheels, our spirits will be clogged with weariness.... Reader, let us put this question--do you serve the Lord with gladness? Let us show to the people of the world, who think our religion to be slavery, that it is to us a delight and a joy! Let our gladness proclaim that we serve a good Master."
~Charles H. Spurgeon
